IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 142,265, dated August 26, 1873 application filed July 21, 1873.

To all whom it may concern:

Be it known that I, WILLIAM PARKER, of Rolla, Phelps county, Missouri, have invented a certain new and useful Improvement in Washing-Machines, of which the following is a specification:

- This invention relates to an improvement on patent 133,049, granted to me November 12, 1872. The improvement consists in supporting the free edge of the board G by suspension-rods whose upper ends are connected to the oscillating side bars D. This arrangement dispenses with the springs g of the said patent, and makes the movements of the board G positive in relation tothat D in its vertical movements, so that they must always be in clined board fixed at one end of the same, and

having horizontal flutes and ribs. 0 is a pivot-bar, havng pivot-bearing in the ears 0,

secured to the sides of the box.- This pivotbar passes through slots 01 in the side bars D of the oscillating wash-board D, the bar 0 forming the axis of oscillation for the board. D. E E are the levers, whichadmit of oscillation on the bar 0. The end of the levers E E are connectedbya hand-bar, 6; they act upon the board D to oscillate it by means of the braces F F, whose ends are pivoted, respectively, in the levers E E and side bars D D. A

The parts thus far are substantially similar to those described in my former patent, No. 133,049; but in this improvement the springs g are dispensed with, and a single spring, 0, is made to perform the office of the two springs c c of that patent.

Upon the outer side of each of the bars D is secured a segment, H, having a segmental slot, h, in which works a button or anti-friction roller, z, upon the inturned end of the suspension-rod I. The lower end of each suspension-rod is pivoted to the board Gr, so as to hold up the said board to near contact with the lower edge of the board D. These suspension-rods I may slide in guides J, secured to the sides of the box A. The top side of the board G is so curved that, as the board D swings over it in its ordinary movements, the distance between the top of the board G and the lower edge of the board D shall be about uniform.

As the board D oscillates the roller or button 2' travels back and forth in the slot 7;, the suspension-rods remaining vertical and supporting the board G in one position during the oscillation of the board D.

It will be seen that when the boards B D are in contact, and the lovers E E are still further depressed, causing the board D to descend edgewise, the suspension-rods (their upper ends being secured to the side bars D D) will descend with the board D, and

allow the board G also to descend; and as the board D again rises, the bottom board G is drawn up with it. The boards D and G are raised after each said descent by a spring, 0, which rests upon the middle of the pivotbar 0, and whose upper end bears against the lower side of the cross-bar K, connecting the upper ends of the side bars D. It is a guidepin secured to the bar 0 or K, and passing axially through the spring and through the other bar.

I claim as new and of my invention The combination of the oscillating board and frame D D, the suspension-rods I, and bottom board G, all arranged and operating substantially as set forth.

WILLIAM PARKER.
